October 13, 2014 and U.S. Serial No. 62/085, 127 filed November 26, 2014, each of which is herein incorporated by reference in their entirety.

1. FIELD

[0001] Provided herein are biomarkers for use in predicting the clinical sensitivity of a solid tumor, and a subject's response to treatment with an immunomodulatory agent, such as 3-(5- amino-2-methyl-4-oxo-4H-quinazolin-3-yl)-piperidine-2,6-dione ("Compound A").

2. BACKGROUND 2.1 Solid Tumors

[0002] A solid tumor is an abnormal mass of tissue that usually does not contain cysts or liquid areas. Solid tumors may be benign or malignant. A solid tumor grows in an anatomical site outside the bloodstream (in contrast, for example, to cancers of hematopoietic origin such as leukemias) and requires the formation of small blood vessels and capillaries to supply nutrients, etc. to the growing tumor mass. Solid tumors are named for the type of cells that form them. Non-limiting examples of solid tumors are sarcomas, carcinomas (epithelial tumors),

melanomas, and glioblastomas. Exemplary solid tumors include biliary cancer (e.g.,

cholangiocarcinoma), bladder cancer, breast cancer (e.g., adenocarcinoma of the breast, papillary carcinoma of the breast, mammary cancer, medullary carcinoma of the breast), brain cancer (e.g., meningioma; glioma, e.g., astrocytoma, oligodendroglioma, glioblastomas; medulloblastoma), cervical cancer (e.g., cervical adenocarcinoma), colorectal cancer (e.g., colon cancer, rectal cancer, colorectal adenocarcinoma), gastric cancer (e.g., stomach adenocarcinoma),

gastrointestinal stromal tumor (GIST), head and neck cancer (e.g. , head and neck squamous cell carcinoma, oral cancer (e.g., oral squamous cell carcinoma (OSCC)), kidney cancer (e.g., nephroblastoma a.k.a. Wilms' tumor, renal cell carcinoma), liver cancer (e.g., hepatocellular cancer (HCC), malignant hepatoma), lung cancer (e.g., bronchogenic carcinoma, small cell lung cancer (SCLC), non-small cell lung cancer (NSCLC), adenocarcinoma of the lung),

neuroblastoma, neurofibroma (e.g., neurofibromatosis (NF) type 1 or type 2, schwannomatosis), neuroendocrine cancer (e.g., gastroenteropancreatic neuroendocrine tumor (GEP-NET), carcinoid tumor), osteosarcoma, ovarian cancer (e.g., cystadenocarcinoma, ovarian embryonal carcinoma, ovarian adenocarcinoma), pancreatic cancer (e.g., pancreatic andenocarcinoma, intraductal papillary mucinous neoplasm (IPMN)), prostate cancer (e.g., prostate

adenocarcinoma), skin cancer (e.g., squamous cell carcinoma (SCC), keratoacanthoma ( A), melanoma, basal cell carcinoma (BCC)) and soft tissue sarcoma (e.g. , malignant fibrous histiocytoma (MFH), liposarcoma, malignant peripheral nerve sheath tumor (MPNST), chondrosarcoma, fibrosarcoma, myxosarcoma, osteosarcoma).

2.2 Hepatocellular carcinoma (HCC)

[0003] HCC, also known as malignant hepatoma, is the most common primary malignancy of the liver and accounts for 80-90% of primary liver tumors. HCC is one of the most common and devastating malignant diseases worldwide, responsible for more than 1 million deaths annually in the world (Parkin et al, CA Cancer J. Clin. 1999, 49, 33-64; Bruix et al., Cancer Cell 2004, 5, 215-219).

[0004] The major risk factors for the development of HCC include hepatitis B or C viral infection, and alcoholic liver disease (Rustgi, Gastroenterol. Clin. North Am. 1987, 16, 545-551; Bosch et al, Semin. Liver Dis. 1999, 19, 271-285; Bosch et al, Gastroenterology 2004, 127, S5- S16; Moradpour et al, Eur. J. Gastro & Hepatol. 2005, 17, 477-483; Koike et al., J.

Gastroenterol. Hepatol. 2008, 23, S87-S91; de Oliveria Andrade, J. Glob. Infect. Dis. 2009, 1, 33-37). HCC arises most commonly in cirrhotic livers following infection with hepatitis B virus (HBV) or hepatitis C virus (HCV) (Liaw, Semin. Liver Dis. 2005, 25, AQ-ΑΊ; Koike Clin.

Gastroenterol. Hepatol. 2005, 3, 132-135). HCC is associated with HBV infection in about 50%> of cases (Liaw, Semin. Liver Dis. 2005, 25, 40-47). HCV infection is the cause of 70%> of the cases of HCC in Japan (Hasan, et al, Hepatology, 1990, 12:589-591; El-Serag et al, N. Engl. J. Med. 1999, 340, 745-750). The HCC incidence has been increasing in Western countries in recent years due to the spread of hepatitis C virus (HCV) infection (El-Serag, Hepatology 2002, 36, S74-83; Trevisani et al, Carcinogenesis 2008, 29, 1299-1305). [0005] HCC is a disease of worldwide significance, of which there is no truly effective therapy, particularly for advanced disease. Therefore, there is a need for biomarkers to aid a HCC treatment and a method of predicting the responsiveness of a HCC subject to a HCC treatment, e.g., chemotherapy.

2.3 Glioblastoma (GBM)

[0006] Glioblastomas (GBM) are tumors that arise from astrocytes or supportive tissue of the brain. Glioblastomas are generally found in the cerebral hemispheres of the brain, but can be found anywhere in the brain or spinal cord. These tumors are usually highly malignant

(cancerous) because the cells reproduce quickly and they are supported by a large network of blood vessels. Glioblastomas usually contain a mix of cell types. It is common for these tumors to contain cystic mineral, calcium deposits, blood vessels, or a mixed grade of cells. There are two types of glioblastomas. The first type of glioblastoma is primary or de novo. The tumors of the first type are very aggressive, and tend to form and make their presence quickly. The second type of glioblastoma is secondary. These tumors have a longer, somewhat slower growth history, yet aggressive. They may begin as lower-grade tumors which eventually become higher grade. The symptoms of glioblastomas are usually caused by increased pressure in the brain, including headache, nausea, vomiting, and drowsiness. Like many tumor types, the exact cause of glioblastoma is not known. The glioblastomas usually contain many different types of cells— some cells may respond well to certain therapies, while others may not be affected at all, thus they are usually difficult to treat and the treatment usually involve combinations of various approaches.

2.4 Cereblon

[0007] At least two iso forms of the protein cereblon (CRBN) exist, which are 442 and 441 amino acids long, respectively, and CRBN is conserved from plant to human. In humans, the CRBN gene has been identified as a candidate gene of an autosomal recessive nonsyndromic mental retardation (ARNSMR). See Higgins, J.J. et al., Neurology, 2004, 63: 1927-1931. CRBN was initially characterized as an RGS -containing novel protein that interacted with a calcium- activated potassium channel protein (SLOl) in the rat brain, and was later shown to interact with a voltage-gated chloride channel (CIC-2) in the retina with AMPKl and DDBl . See Jo, S. et al., J. Neurochem, 2005, 94: 1212-1224; Hohberger B. et al, FEBS Lett, 2009, 583:633-637; Angers S. et al, N ^' ature, 2006, 443:590-593. DDB1 was originally identified as a nucleotide excision repair protein that associates with damaged DNA binding protein 2 (DDB2). Its defective activity causes the repair defect in the patients with xeroderma pigmentosum complementation group E (XPE). DDB1 also appears to function as a component of numerous distinct DCX (DDBl-CUL4-X-box) E3 ubiquitin-protein ligase complexes which mediate the ubiquitination and subsequent proteasomal degradation of target proteins. CRBN has also been identified as a target for the development of therapeutic agents for diseases of the cerebral cortex. See WO 2010/137547 Al .

[0008] CRBN has recently been identified as a key molecular target that binds to thalidomide to cause birth defects. See Ito, T. et al, Science, 2010, 327: 1345-1350. DDB1 was found to interact with CRBN and, thus, was indirectly associated with thalidomide. Moreover, thalidomide was able to inhibit auto-ubiquitination of CRBN in vitro, suggesting that

thalidomide is an E3 ubiquitin-ligase inhibitor. Id. Importantly, this activity was inhibited by thalidomide in wild-type cells, but not in cells with mutated CRBN binding sites that prevent thalidomide binding. Id. The thalidomide binding site was mapped to a highly conserved C- terminal 104 amino acid region in CRBN. Id. Individual point mutants in CRBN, Y384A and W386A were both defective for thalidomide binding, with the double point mutant having the lowest thalidomide-binding activity. Id. A link between CRBN and the teratogenic effect of thalidomide was confirmed in animal models of zebra-fish and chick embryos. Id.

[0009] Whether binding to CRBN, the CRBN E3 ubiquitin-ligase complex, or one or more substrates of CRBN, is required for the beneficial effects of thalidomide and other drugs is yet to be established. Understanding these interactions with thalidomide and other drug targets will allow the definition of the molecular mechanisms of efficacy and/or toxicity and may lead to drugs with improved efficacy and toxicity profiles.

2.5 Compounds

[0010] A number of studies have been conducted with the aim of providing compounds that can safely and effectively be used to treat diseases associated with abnormal production of TNF- a. See, e.g., Marriott, J.B., et al, Expert Opin. Biol. Ther., 2001, 1(4): 1-8; G.W. Muller, et al., J Med Chem., 1996, 39(17): 3238-3240; and G.W. Muller, et al, Bioorg & Med Chem Lett., 1998, 8: 2669-2674. Some studies have focused on a group of compounds selected for their capacity to potently inhibit TNF-a production by LPS stimulated PBMC. L.G. Corral, et al., Ann. Rheum. Dis., 1999, 58:(Suppl I) 1107-1113. These compounds show not only potent inhibition of TNF-a but also marked inhibition of LPS induced monocyte IL1B and IL12 production. LPS induced IL6 is also inhibited by such compounds, albeit partially. These compounds are potent stimulators of LPS induced IL10. Id.

[0011] Compounds for the methods provided herein include, but are not limited to, the substituted 2-(2,6-dioxopiperidin-3-yl) phthalimides and substituted 2-(2,6-dioxopiperidin-3-yl)- 1-oxoisoindoles described in U.S. Patent Nos. 6,281,230 and 6,316,471, both to G.W. Muller, et al. Still other specific compounds disclosed herein belong to a class of isoindole-imides disclosed in U.S. Patent Nos. 6,395,754, 6,555,554, 7,091,353, U.S. Publication No.

2004/0029832, and International Publication No. WO 98/54170, each of which is incorporated herein by reference.

[0012] Thalidomide, lenalidomide and pomalidomide have shown remarkable responses in patients with multiple myeloma, lymphoma and other hematological diseases such as myelodysplasia syndrome. See Galustian C, et al, Expert Opin Pharmacother., 2009, 10: 125- 133. These treatment compounds display a broad spectrum of activity, including anti-angiogenic properties, modulation of pro-inflammatory cytokines, co-stimulation of T cells, increased NK cell toxicity, direct anti-tumor effects and modulation of stem cell differentiation.

[0013] For example, thalidomide and lenalidomide have emerged as important options for the treatment of multiple myeloma in newly diagnosed patients, in patients with advanced disease who have failed chemotherapy or transplantation, and in patients with relapsed or refractory multiple myeloma. Lenalidomide in combination with dexamethasone has been approved for the treatment of patients with multiple myeloma who have received at least one prior therapy. Pomalidomide may also be administered in combination with dexamethasone. U.S. Patent Publication No. 2004/0029832 Al, the disclosure of which is hereby incorporated in its entirety, discloses the treatment of multiple myeloma.

[0014] Another compound provided herein is 3-(5-amino-2-methyl-4-oxo-4H-quinazolin-3- yl)-piperidine-2,6-dione ("Compound A"), which has the following structure:

A

or an enantiomer or a mixture of enantiomers thereof; or a pharmaceutically acceptable salt, solvate, hydrate, co-crystal, clathrate, or polymorph thereof.

[0015] Compound A can be prepared as described in U.S. Pat. No. 7,635,700, the disclosure of which is incorporated herein by reference in its entirety. The compound can be also synthesized according to other methods apparent to those of skill in the art based upon the teaching herein. In certain embodiments, Compound A is in a crystalline form described in U.S. Provisional Pat. App. No. 61/451,806, filed March 11, 2011, which is incorporated herein by reference in its entirety. In some embodiments, the hydrochloride salt of Compound A is used in the methods provided herein. Methods of treating, preventing and/or managing cancers and other diseases using Compound A are described in U.S. Provisional Pat. App. No. 61/451,995, filed March 11, 2011, which is incorporated herein by reference in its entirety.

[0016] Yet another compound provided herein is 3-[4-(4-Morpholin-4-ylmethyl-benzyloxy)- l-oxo-l,3-dihydro-isoindol-2-yl]-piperidine-2,6-dione (Compound B), which has the following structure:

B or an enantiomer or a mixture of enantiomers thereof; or a pharmaceutically acceptable salt, solvate, hydrate, co-crystal, clathrate, or polymorph thereof. [0017] The conventional methods of assessing the effects of immunomodulatory compounds require live cellular assays or lengthy clinical endpoints. These cellular tests are cumbersome and often require the use of various stimulants (e.g., lipopolysaccharide or anti-CD3 antibody).

Indirect endpoints such as cytokine production are evaluated, which can be influenced via multiple pathways. Further, clinical efficacy of these compounds could not be correctly predicted, as it could only be measured in terms of patient response, which usually requires a minimum of several months of treatment. In view of the deficiencies of the conventional methods, there is a need to develop an efficient, sensitive and accurate method to detect, quantify and characterize the pharmacodynamic activity of immunomodulatory compounds.

4. DETAILED DESCRIPTION

[0051] The methods, arrays, probes, and kits provided herein are based, in part, on the discovery that a changed level, e.g., an increased level and/or a decreased level, of certain molecules (e.g. , mRNAs, cDNA, or proteins) in a biological sample can be utilized as biomarkers to predict responsiveness of a subject having or suspected to have a solid tumor to a treatment compound, e.g. , thalidomide, lenalidomide, pomalidomide, Compound A, or

Compound B, or a stereoisomer thereof, or a pharmaceutically acceptable salt, solvate, hydrate, co-crystal, clathrate, or a polymorph thereof.

[0052] In certain embodiments, the methods provided herein are based on comparison of the level of one or more biomarkers in a biological sample from a subject having or suspected to have a solid tumor to a reference level of the biomarkers or the level of a control. The biomarker level is used to determine or to predict, for example, the likelihood of the subject's

responsiveness to a treatment compound, such as thalidomide, lenalidomide, pomalidomide, Compound A, or Compound B, or a stereoisomer thereof, or a pharmaceutically acceptable salt, solvate, hydrate, co-crystal, clathrate, or a polymorph thereof. 4.1 Brief Description of Figures

4.2 Definitions

[0060] The term "treat," "treating," or "treatment" refers to alleviating or abrogating a disease, e.g., HCC or GBM, or one or more of the symptoms associated with the disease; or alleviating or eradicating the cause(s) of the disease itself.

[0061] As used herein "solid tumor" refers to an abnormal mass of tissue. Solid tumors may be benign or malignant. A solid tumor grows in an anatomical site outside the bloodstream (in contrast, for example, to cancers of hematopoietic origin such as leukemias) and requires the formation of small blood vessels and capillaries to supply nutrients, etc. to the growing tumor mass. Solid tumors are named for the type of cells that form them. Non- limiting examples of solid tumors are sarcomas, carcinomas (epithelial tumors), melanomas, and glioblastomas.

Exemplary solid tumors include, but are not limited to, biliary cancer (e.g., cholangiocarcinoma), bladder cancer, breast cancer (e.g., adenocarcinoma of the breast, papillary carcinoma of the breast, mammary cancer, medullary carcinoma of the breast), brain cancer (e.g., meningioma; glioma, e.g., astrocytoma, oligodendroglioma, glioblastomas; medulloblastoma), cervical cancer (e.g., cervical adenocarcinoma), colorectal cancer (e.g., colon cancer, rectal cancer, colorectal adenocarcinoma), gastric cancer (e.g. , stomach adenocarcinoma), gastrointestinal stromal tumor (GIST), head and neck cancer (e.g., head and neck squamous cell carcinoma, oral cancer (e.g., oral squamous cell carcinoma (OSCC)), kidney cancer (e.g., nephroblastoma a.k.a. Wilms' tumor, renal cell carcinoma), liver cancer (e.g., hepatocellular cancer (HCC), malignant hepatoma), lung cancer (e.g., bronchogenic carcinoma, small cell lung cancer (SCLC), non-small cell lung cancer (NSCLC), adenocarcinoma of the lung), neuroblastoma, neurofibroma (e.g., neurofibromatosis (NF) type 1 or type 2, schwannomatosis), neuroendocrine cancer (e.g., gastroenteropancreatic neuroendoctrine tumor (GEP-NET), carcinoid tumor), osteosarcoma, ovarian cancer (e.g. , cystadenocarcinoma, ovarian embryonal carcinoma, ovarian

adenocarcinoma), pancreatic cancer (e.g. , pancreatic andenocarcinoma, intraductal papillary mucinous neoplasm (IPMN)), prostate cancer (e.g., prostate adenocarcinoma), skin cancer (e.g., squamous cell carcinoma (SCC), keratoacanthoma ( A), melanoma, basal cell carcinoma (BCC)) and soft tissue sarcoma (e.g., malignant fibrous histiocytoma (MFH), liposarcoma, malignant peripheral nerve sheath tumor (MPNST), chondrosarcoma, fibrosarcoma, myxosarcoma, osteosarcoma).

[0062] The term "therapeutically effective amount" of a compound refers to the amount of a compound that, when administered, is sufficient to prevent development of, or alleviate to some extent, one or more of the symptoms of a disease, e.g., HCC or GBM, being treated. The term also refers to the amount of a compound that is sufficient to elicit the biological or medical response of a biological molecule (e.g., a protein, enzyme, R A, or DNA), cell, tissue, system, animal, or human, which is being sought by a researcher, veterinarian, medical doctor, or clinician. Furthermore, a therapeutically effective amount of a compound means an amount of a therapeutic agent, alone or in combination with other therapies, which provides a therapeutic benefit in the treatment or management of a disease, e.g., HCC or GBM. The term encompasses an amount that improves overall therapy, reduces, or avoids symptoms or causes of a disease, e.g., HCC or GBM, or enhances the therapeutic efficacy of another therapeutic agent.

[0063] The term "level" refers to the amount, accumulation, or rate of a biomarker molecule. A level can be represented, for example, by the amount or the rate of synthesis of a massager RNA (mPvNA) encoded by a gene, the amount or the rate of synthesis of a polypeptide or protein encoded by a gene, or the amount or the rate of synthesis of a biological molecule accumulated in a cell or biological fluid. The term "level" refers to an absolute amount of a molecule in a sample or to a relative amount of the molecule, determined under steady-state or non-steady-state conditions. [0064] The term "responsiveness" or "responsive" when used in reference to a treatment refer to the degree of effectiveness of the treatment in lessening or decreasing the symptoms of a disease, e.g., HCC or GBM, being treated. For example, the term "increased responsiveness" when used in reference to a treatment of a cell or a subject refers to an increase in the

effectiveness in lessening or decreasing the symptoms of the disease when measured using any methods known in the art. In certain embodiments, the increase in the effectiveness is at least about 5%, at least about 10%, at least about 20%, at least about 30%, at least about 40%, or at least about 50%>.

[0065] As used herein, the terms "effective subject response," "effective patient response," or "effective patient tumor response" refers to any increase in the therapeutic benefit to the patient. An "effective patient tumor response" can be, for example, a 5%, 10%>, 15%, 20%>, 25%, 30%, 40%, 50%, 60%, 70%, 80%, 90%,or 100% decrease in the rate of progress of the tumor. An "effective patient tumor response" can be, for example, a 5%, 10%, 15%, 20%, 25%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, or 100% decrease in the physical symptoms of a cancer. An "effective patient tumor response" can be, for example, a 5%, 10%, 15%, 20%, 25%, 30%, 40%, 50%, 60%, 70%, 80%, 90%,or 100% decrease in the size of a tumor. An "effective patient tumor response" can be, for example, a 5%, 10%, 15%, 20%, 25%, 30%, 40%, 50%, 60%, 70%, 80%), 90%,or 100%) decrease in the physical symptoms of a cancer or the tumor size. An

"effective patient tumor response" can also be, for example, a 5%, 10%, 15%, 20%, 25%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, 200%, or more increase in the response of the patient, as measured by any suitable means, such as gene expression, cell counts, assay results, etc.

[0066] The term "likelihood" refers to an increase in the probability of an event. The term "likelihood" when used in reference to the effectiveness of a subject response to a treatment of a disease, e.g., HCC or GBM, contemplates an increased probability that the symptoms of the disease will be lessened or decreased.

[0067] The term "predict" generally means to determine or tell in advance. When used to "predict" the effectiveness of the treatment of a disease {e.g., HCC or GBM), for example, the term "predict" can mean that the likelihood of the outcome of the treatment can be determined at the outset, before the treatment has begun, or before the treatment period has progressed substantially.

[0068] The term "polypeptide," "protein," or "peptide," as used herein interchangeably, refers to a polymer of two or more amino acids in a serial array, linked through one or more peptide bond(s). The term encompasses proteins, protein fragments, protein analogues, oligopeptides, and peptides. The amino acids of the polypeptide, protein, or peptide can be naturally occurring amino acids or synthetic amino acids (e.g., mimics of naturally occurring amino acids). The polypeptide, protein, or peptide can be made synthetically or purified from a biological sample. The polypeptide, protein, or peptide also encompasses modified

polypeptides, proteins, and peptides, , e.g., a glycopolypeptide, glycoprotein, or glycopeptide; or a lipopolypeptide, lipoprotein, or lipopeptide.

[0069] The term "antibody" refers to a polypeptide that specifically binds an epitope (e.g., an antigen). The term "antibody" is used herein in the broadest sense and covers fully assembled antibodies, antibody fragments which retain the ability to specifically bind to an antigen (e.g. , Fab, F(ab')₂, Fv, and other fragments), single chain antibodies, diabodies, antibody chimeras, hybrid antibodies, bispecific antibodies, and humanized antibodies. The term "antibody" also covers both polyclonal and monoclonal antibodies.

[0070] The term "expressed" or "expression" refers to the transcription from a gene to give an RNA nucleic acid molecule, e.g., mRNA, at least complementary in part to a region of one of the two nucleic acid strands of the gene. The term "expressed" or "expression" as used herein also refers to the translation from an RNA molecule to give a protein, a polypeptide or a portion thereof.

[0071] A biological marker or "biomarker" is a substance whose detection indicates a particular biological state, such as, for example, the presence of cancer. In some embodiments, biomarkers can either be determined individually, or several biomarkers can be measured simultaneously. [0072] A "biomarker" can indicate a change in the level of mR A expression that may correlate with the risk or progression of a disease, or with the susceptibility of the disease to a given treatment. The biomarker is a nucleic acid, such as a mRNA or cDNA.

[0073] A "biomarker" can indicate a change in the level of polypeptide or protein expression that may correlate with the risk, susceptibility to treatment, or progression of a disease. In some embodiments, the biomarker can be a polypeptide or protein, or a fragment thereof. The relative level of specific proteins can be determined by methods known in the art. For example, antibody based methods, such as an immunoblot, enzyme-linked immunosorbent assay (ELISA), or other methods can be used.

[0074] An mRNA that is "upregulated" is generally increased upon a given treatment or condition. An mRNA that is "downregulated" generally refers to a decrease in the level of expression of the mRNA in response to a given treatment or condition. In some situations, the mRNA level can remain unchanged upon a given treatment or condition. An mRNA from a patient sample can be "upregulated" when treated with a drug, as compared to a non-treated control. This upregulation can be, for example, an increase of about 5%, 10%, 20%>, 30%>, 40%>, 50%, 60%, 70%, 90%, 100%, 200%, 300%, 500%, 600%, 700%, 800%, 900%, 1,000%, 1,500%, 2,000%, 2,500%, 3,00%, 3,500%, 4,000%, 4,500%, 5,000% or more of the comparative control mRNA level. Alternatively, an mRNA can be "downregulated", or expressed at a lower level, in response to administration of certain compounds or other agents. A downregulated mRNA can be, for example, present at a level of about 99%, 95%, 90%, 85%, 80%, 75%, 70%, 65%, 60%, 55%, 50%, 45%, 40%, 35%, 30%, 25%, 20%, 15%, 10%, 5%, 3%, 1% or less of the

comparative control mRNA level.

[0075] Similarly, the level of a polypeptide or protein biomarker from a patient sample can be increased when treated with a drug, as compared to a non-treated control. This increase can be about 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, 200%, 300%, 400%, 500%, 700%, 1,000%, 1 ,500%, 2,000%, 2,500%, 3,000%, 3,500%, 4,000%, 4,500%, 5,000% or more of the comparative control protein level. Alternatively, the level of a protein biomarker can be decreased in response to administration of certain compounds or other agents. This decrease can be, for example, present at a level of about 99%, 95%, 90%, 80%, 70%, 60%, 50%, 40%, 30%), 20%), 10%), 5%o, 3%o, 1%) or less of the comparative control protein level.

[0076] The terms "determining", "measuring", "evaluating", "assessing" and "assaying" are used interchangeably herein to refer to a form of measurement, including determining if an element is present or not. The measurement can be quantitative and/or qualitative

determinations. "Assessing the presence of can include determining the amount of something present, as well as determining whether it is present or absent.

[0077] The terms "nucleic acid" and "polynucleotide" are used interchangeably herein to refer to a polymer of nucleotides, e.g., deoxyribonucleotides or ribonucleotides, or compounds, which can hybridize with a naturally occurring nucleic acid in a sequence specific manner analogous to that of two naturally occurring nucleic acids, e.g., participating in Watson-Crick base pairing interactions. As used herein in the context of a polynucleotide sequence, the term "bases" (or "base") is synonymous with "nucleotides" (or "nucleotide"), i.e., the monomer subunit of a polynucleotide. The terms "nucleoside" and "nucleotide" are intended to include those moieties that contain not only the known purine and pyrimidine bases, but also other heterocyclic bases that have been modified. Such modifications include methylated purines or pyrimidines, acylated purines or pyrimidines, alkylated riboses or other heterocycles. In addition, the terms "nucleoside" and "nucleotide" include those moieties that contain not only

conventional ribose and deoxyribose sugars, but other sugars as well. Modified nucleosides or nucleotides also include modifications on the sugar moiety, e.g., wherein one or more of the hydroxyl groups are replaced with halogen atoms or aliphatic groups, or are functionalized as ethers, amines, or the like. The term "analogue" of a "nucleic acid" or "polynucleotide" refers to a molecule having a structural feature that is recognized in the literature as being a mimetic, derivative, having an analogous structure, or other like terms, and includes, for example, a polynucleotide incorporating a non-natural nucleotide, a nucleotide mimetic such as a 2'- modified nucleoside, peptide nucleic acid, oligomeric nucleoside phosphonate, and any polynucleotide that has added substituent groups, such as protecting groups or linking moieties.

[0078] The term "complementary" refers to specific binding between polynucleotides based on the sequences of the polynucleotides. As used herein, a first polynucleotide and a second polynucleotide are complementary if they bind to each other in a hybridization assay under stringent conditions, e.g., if they produce a given or detectable level of signal in a hybridization assay. Portions of polynucleotides are complementary to each other if they follow conventional base-pairing rules, e.g., A pairs with T (or U) and G pairs with C, although small regions (e.g. less than about 3 bases) of mismatch, insertion, or deleted sequence may be present.

[0079] The term "sequence identity" or "identity" in the context of two nucleic acid sequences refers to the residues in the two sequences which are the same when aligned for maximum correspondence over a specified comparison window, and can take into consideration additions, deletions and substitutions.

[0080] The term "substantial identity" or "homologous" in their various grammatical forms in the context of polynucleotides generally means that a polynucleotide comprises a sequence that has a desired identity, for example, at least 60%, at least 70%>, at least 80%>, at least 90%> and at least 95% sequence identity, compared to a reference sequence. Another indication that nucleotide sequences are substantially identical is if two molecules hybridize to each other under stringent conditions.

[0081] As used herein, the term "bound" can be used herein to indicate direct or indirect attachment. In the context of chemical structures, "bound" (or "bonded") may refer to the existence of a chemical bond directly joining two moieties or indirectly joining two moieties (e.g., via a linking group or any other intervening portion of the molecule). The chemical bond may be a covalent bond, an ionic bond, a coordination complex, hydrogen bonding, van der Waals interactions, or hydrophobic stacking, or may exhibit characteristics of multiple types of chemical bonds. In certain instances, "bound" includes embodiments where the attachment is direct and also embodiments where the attachment is indirect.

[0082] The terms "isolated" and "purified" refer to isolation of a substance (such as mR A or protein) such that the substance comprises a substantial portion of the sample in which it resides, i.e., greater than the substance is typically found in its natural or un-isolated state.

Typically, a substantial portion of the sample comprises, e.g., greater than about 1%, greater than about 2%, greater than about 5%, greater than about 10%, greater than about 20%, greater than about 50%), or more, usually up to about 90%> to 100%) of the sample. For example, a sample of isolated mRNA can typically comprise at least about 1% total mRNA. Techniques for purifying polynucleotides are well known in the art and include, for example, gel electrophoresis, ion- exchange chromatography, affinity chromatography, flow sorting, and sedimentation according to density.

[0083] The term "biological sample" as used herein refers to a sample obtained from a biological subject, including a sample of biological tissue or fluid origin, obtained, reached, or collected in vivo or in situ. A biological sample also includes samples from a region of a biological subject containing precancerous or cancer cells or tissues. Such samples can be, but are not limited to, organs, tissues, fractions and cells isolated from a mammal. Exemplary biological samples include, but are not limited to, cell lysate, a cell culture, a cell line, a tissue, oral tissue, gastrointestinal tissue, an organ, an organelle, a biological fluid, a blood sample, a urine sample, a skin sample, and the like. In certain embodiments, biological samples include, but are not limited to, whole blood, partially purified blood, PBMCs, tissue biopsies, and the like.

[0084] The term "analyte" as used herein, refers to a known or unknown component of a sample.

[0085] The term "capture agent," as used herein, refers to an agent that binds an mRNA or protein through an interaction that is sufficient to permit the agent to bind and concentrate the mRNA or protein from a homogeneous mixture.

[0086] The term "probe" as used herein, refers to a capture agent that is directed to a specific target mRNA biomarker sequence. Accordingly, each probe of a probe set has a respective target mRNA biomarker. A probe/target mRNA duplex is a structure formed by hybridizing a probe to its target mRNA biomarker.

[0087] The term "nucleic acid probe" or "oligonucleotide probe" refers to a nucleic acid capable of binding to a target nucleic acid of complementary sequence, such as the mRNA biomarkers provided herein, through one or more types of chemical bonds, usually through complementary base pairing, usually through hydrogen bond formation. As used herein, a probe may include natural {e.g., A, G, C, or T) or modified bases (7-deazaguanosine, inosine, etc.). In addition, the bases in a probe may be joined by a linkage other than a phosphodiester bond, so long as it does not interfere with hybridization. It will be understood by one of skill in the art that probes may bind target sequences lacking complete complementarity with the probe sequence depending upon the stringency of the hybridization conditions. The probes are preferably directly labeled with isotopes, for example, chromophores, lumiphores, chromogens, or indirectly labeled with biotin to which a streptavidin complex may later bind. By assaying for the presence or absence of the probe, one can detect the presence or absence of a target mRNA biomarker of interest.

[0088] The term "stringent assay conditions" refers to conditions that are compatible to produce binding pairs of nucleic acids, e.g., probes and target mRNAs, of sufficient

complementarity to provide for the desired level of specificity in the assay while being generally incompatible to the formation of binding pairs between binding members of insufficient complementarity to provide for the desired specificity. The term "stringent assay conditions" generally refers to the combination of hybridization and wash conditions.

[0089] A "label" or a "detectable moiety" in reference to a nucleic acid, refers to a composition that, when linked with a nucleic acid, renders the nucleic acid detectable, for example, by spectroscopic, photochemical, biochemical, immunochemical, or chemical means. Exemplary labels include, but are not limited to, radioactive isotopes, magnetic beads, metallic beads, colloidal particles, fluorescent dyes, enzymes, biotin, digoxigenin, haptens, and the like. A "labeled nucleic acid or oligonucleotide probe" is generally one that is bound, either covalently, through a linker or a chemical bond, or noncovalently, through ionic bonds, van der Waals forces, electrostatic attractions, hydrophobic interactions, or hydrogen bonds, to a label such that the presence of the nucleic acid or probe can be detected by detecting the presence of the label bound to the nucleic acid or probe.

[0090] The terms "polymerase chain reaction" or "PCR," as used herein generally refers to a procedure wherein small amounts of a nucleic acid, RNA and/or DNA, are amplified as described, for example, in U.S. Pat. No. 4,683,195 to Mullis. Generally, sequence information from the ends of the region of interest or beyond needs to be available, such that oligonucleotide primers can be designed; these primers will be identical or similar in sequence to opposite strands of the template to be amplified. The 5' terminal nucleotides of the two primers may coincide with the ends of the amplified material. PCR can be used to amplify specific RNA sequences, specific DNA sequences from total genomic DNA, and cDNA transcribed from total cellular RNA, bacteriophage or plasmid sequences, etc. See generally Mullis et al., Cold Spring Harbor Symp. Quant. Biol, 51 : 263 (1987); Erlich, ed., PCR Technology, (Stockton Press, NY, 1989).

[0091] The term "cycle number" or "CT" when used herein in reference to PCR methods, refers to the PCR cycle number at which the fluorescence level passes a given set threshold level. The CT measurement can be used, for example, to approximate levels of mRNA in an original sample. The CT measurement is often used in terms of "dCT" or the "difference in the CT" score, when the CT of one nucleic acid is subtracted from the CT of another nucleic acid.

[0092] The term "about" or "approximately" means an acceptable error for a particular value as determined by one of ordinary skill in the art, which depends in part on how the value is measured or determined. In certain embodiments, the term "about" or "approximately" means within 1, 2, 3, or 4 standard deviations. In certain embodiments, the term "about" or

"approximately" means within 50%, 20%, 15%, 10%, 9%, 8%, 7%, 6%, 5%, 4%, 3%, 2%, 1%, 0.5%), or 0.05%) of a given value or range.

[0093] The practice of the embodiments provided herein will employ, unless otherwise indicated, conventional techniques of molecular biology, microbiology, and immunology, which are within the skill of those working in the art. Such techniques are explained fully in the literature. Examples of particularly suitable texts for consultation include the following:

4.3 Biomarkers [0094] A biological marker or "biomarker" is a substance, the change and/or the detection of which indicates a particular biological state, such as, for example, the responsiveness of a disease, e.g., HCC or GBM, to a given treatment, e.g., a treatment by a treatment compound, e.g., thalidomide, lenalidomide, pomalidomide, Compound A, or Compound B, or a stereoisomer thereof, or a pharmaceutically acceptable salt, solvate, hydrate, co-crystal, clathrate, or a polymorph thereof.

[0095] The present application is based, in part, on the finding that the levels of certain proteins change in response to treatment compound, e.g., as shown in the proteomics study in the Examples. For example, as shown, certain proteins upregulated in response to Compound A treatment include Nestin, KAT1/CCBL1, and WIBG, and certain proteins downregulated in response to Compound A treatment include MVP, PARP4, ZFP91, and ZNF198. Thus, in some embodiments, the biomarker provided herein is selected from a group consisting of Nestin, KAT1/CCBL1, WIBG, MVP, PARP4, ZFP91, and ZNF198. In some embodiments of the various methods provided herein, the biomarker is selected from a group consisting of Nestin, KAT1/CCBL1, and WIBG.

Thus, in a specific embodiment, the biomarker is ZFP91. ZFP91 zinc finger protein (ZFP91) encodes a 63.4 kDa nuclear protein with structural motifs characteristic of transcription factor, and it is expressed ubiquitously in various cell types and is known to be highly conservative. Paschke et al., Pathol Oncol Res., 2013, 20:453-459. ZFP91 is recognized as an atypical E3 ubiquitin-protein ligase, and mediates a K63-linked

ubiquitination of MAP3K14. Id. It has also been indicated that ZFP91 has implications in various cancers. For example, it has been shown that ZFP91 expression is upregulated in mononuclear cells from patients with acute myelogenous leukemia (AML) and in many neoplastic blood cell lines. In addition, the function of ZFP91 has been shown to relate to cell apoptosis rate. Id. Furthermore, ZFP91 has been shown to interact with ARF tumor suppressor (cyclin-dependent kinase inhibitor 2A, isoform 4), the von Hippel-Lindau tumor suppressor (pVHL) and the hypoxia inducible factor- la (HIF-l ). In some embodiments, the biomarker is an isoform of ZFP91 protein.

[00103] The present disclosure is also based in part on the discovery that Cereblon (CRBN) is up-regulated in solid tumor cell lines, e.g., HCC or GBM, in response to a treatment with treatment compounds provided herein. Thus, in another specific embodiment, the biomarker is CRBN. CRBN is a 442-amino acid protein conserved from plant to human. In humans, the CRBN gene has been identified as a candidate gene of an autosomal recessive nonsyndromic mental retardation (ARNSMR). See Higgins, J.J. et al. , Neurology, 2004, 63 : 1927- 1931. CRBN was initially characterized as an RGS -containing novel protein that interacted with a calcium- activated potassium channel protein (SLOl) in the rat brain, and was later shown to interact with a voltage-gated chloride channel (CIC-2) in the retina with AMPK7 and DDBl . See Jo, S. et al., J. Neurochem, 2005, 94: 1212-1224; Hohberger B. et al, FEBS Lett, 2009, 583:633-637; Angers S. et ah, Nature, 2006, 443:590-593. DDB1 was originally identified as a nucleotide excision repair protein that associates with damaged DNA binding protein 2 (DDB2). Its defective activity causes the repair defect in the patients with xeroderma pigmentosum complementation group E (XPE). DDB1 also appears to function as a component of numerous distinct DCX (DDBl-CUL4-X-box) E3 ubiquitin-protein ligase complexes which mediate the ubiquitination and subsequent proteasomal degradation of target proteins. CRBN has also been identified as a target for the development of therapeutic agents for diseases of the cerebral cortex. See WO 2010/137547 Al . In some embodiments, the biomarker is an isoform of CRBN.

[00113] In some embodiments, the level of the biomarker provided herein correlates with or is indicative of the responsiveness of a disease (e.g., HCC or GBM) to a treatment, e.g., a treatment by a treatment compound, e.g., thalidomide, lenalidomide, pomalidomide, Compound A, or Compound B, or a stereoisomer thereof, or a pharmaceutically acceptable salt, solvate, hydrate, co-crystal, clathrate, or a polymorph thereof.

[00114] In some embodiments, the biomarker is an mR A. In other embodiments, the biomarker is a cDNA. The level of the biomarker can be determined using the methods provided herein.

[00115] In other embodiments, the biomarker is a protein. When a biomarker is a

polypeptide, protein, or peptide, the level of the biomarker can be measured by determining the protein level, the mRNA level, or the enzymatic activity of the biomarker. The level of the biomarker can be determined using the methods provided herein.

[00116] The reference level can be determined by a plurality of methods. In some

embodiments, the reference level is one that a treatment decision is made based on whether a subject having or suspected of having a solid tumor, e.g., HCC or GBM, has the level of the biomarker above the reference level. Subjects who have a level of the biomarker higher than the reference level have a different probability of responsiveness to the treatment than subjects who have a level of the biomarker lower than the reference level. In certain embodiments, the reference level is measured simultaneously with the biological sample from the subject. In some embodiments, the reference level is predetermined.

[00117] In some embodiments, the reference level is determined from a sample from the same subject that contains no solid tumor cells. In other embodiments, the reference level is determined from a sample from a group of subjects that contains no solid tumor cells. In yet other embodiments, the reference level is determined from a sample from a group of subjects who do not have the solid tumor. An increased level or a decreased level of the biomarker correlates positively with increased responsiveness of the subject to a treatment by a treatment compound, e.g., thalidomide, lenalidomide, pomalidomide, Compound A, or Compound B, or a stereoisomer thereof, or a pharmaceutically acceptable salt, solvate, hydrate, co-crystal, clathrate, or a polymorph thereof.

[00118] In some embodiments, the control sample is a sample containing no solid tumor cells from the same subject. In other embodiments, the control sample is a sample of liver cells containing no solid tumor cells from the same subject. In other embodiments, the control sample is a sample containing no solid tumor cells from a group of subjects. In other embodiments, the control sample is a sample of liver cells containing no solid tumor cells from a group of subjects. In yet other embodiments, the control sample is a sample from a subject having no solid tumor. In yet other embodiments, the control sample is a sample of liver cells from a subject having no solid tumor. In yet other embodiments, the control sample is a sample from a group of subjects having no solid tumor. In yet other embodiments, the control sample is a sample of liver cells from a group of subjects having no solid tumor. An increased or a decreased level of the one or more biomarkers as compared with the level of the control sample correlates positively with increased responsiveness of the subject to a treatment by a treatment compound, e.g.,

thalidomide, lenalidomide, pomalidomide, Compound A, or Compound B, or a stereoisomer thereof, or a pharmaceutically acceptable salt, solvate, hydrate, co-crystal, clathrate, or a polymorph thereof.

[00119] In some embodiments, the reference is prepared by using a second tumor cell not treated with the compound. In other embodiments, the reference is prepared by using a second sample obtained from the subject prior to administration of the treatment compound to the patient; and wherein the second sample is from the same source as the sample. In yet other embodiments, the reference is prepared by using a second sample obtained from a healthy subject not having the solid tumor; and wherein the second sample is from the same source as the sample.

[00120] In some embodiments, the biomarkers provided herein are determined individually. In other embodiments, two or more of the biomarkers provided herein are determined

simultaneously. [00121] In some embodiments, the level of a biomarker nucleic acid or polypeptide provided herein is measured in a biological sample from a subject, e.g., a HCC or a GBM cell containing- sample from the subject. In other embodiments, an affinity binding assay is used to measure the level of the biomarker polypeptide. The affinity binding assays that are applicable for use in the methods provided herein include both soluble and solid phase assays.

[00122] An example of a soluble phase affinity binding assay is immunoprecipitation using a biomarker binding agent, e.g., an antibody reactive with the biomarker polypeptide. Examples of solid phase affinity binding assays include immunohistochemical binding assays and

immunoaffinity binding assays. Examples of immunoaffinity binding assays include, but are not limited to, immunohistochemistry methods, immunoblot methods, ELISA and

radioimmunoassay (RIA).

[00123] An antibody useful in the methods provided herein includes a polyclonal and monoclonal antibodies. An antibody useful in the methods provided herein includes naturally occurring antibodies as well as non-naturally occurring antibodies, e.g., single chain antibodies, chimeric antibodies, bifunctional antibodies, humanized antibodies, and antigen-binding fragments thereof.

[00124] The biological sample can be liver tissue or a fluid such as blood, serum, or urine. In certain embodiments, the sample of cells from a subject is obtained via biopsy. Once a level of a biomarker is determined, this value can be correlated with clinical data on the subject from whom the sample is derived, e.g., the responsiveness of a subject to a given treatment.

[00125] In some embodiments, the sample of cells from a subject is obtained via biopsy.

[00126] In some embodiments, the level of only one of the biomarkers is monitored. In other embodiments, the levels of two or more of the biomarkers are monitored simultaneously.

4.5 Methods of Detecting Biomarker Levels

4.5.1 Methods of Detecting mRNA Levels in a Sample

[00412] Several methods of detecting or quantitating mRNA levels are known in the art and are suitable for use in the methods provided herein for measuring the level of the biomarker. Exemplary methods include, but are not limited to, northern blots, ribonuclease protection assays, and PCR-based methods. When the biomarker is an mRNA molecule, the mRNA sequence, or a fragment thereof, can be used to prepare a probe that is at least partially complementary. The probe can then be used to detect the mRNA sequence in a sample, using any suitable assay, such as PCR-based methods, Northern blotting, or a dipstick assay.

[00413] The assay method can be varied depending on the type of mRNA information desired. Exemplary methods include, but are not limited to, Northern blots and PCR-based methods (e.g., qRT-PCR). Methods such as qRT-PCR can also accurately quantitate the amount of the mRNA in a sample.

[00414] Any suitable assay platform can be used to determine the presence of the mRNA in a sample. For example, an assay may be in the form of a dipstick, a membrane, a chip, a disk, a test strip, a filter, a microsphere, a slide, a multiwell plate, or an optical fiber. An assay system may have a solid support on which a nucleic acid corresponding to the mRNA is attached. The solid support may comprise, for example, a plastic, silicon, a metal, a resin, glass, a membrane, a particle, a precipitate, a gel, a polymer, a sheet, a sphere, a polysaccharide, a capillary, a film a plate, or a slide. The assay components can be prepared and packaged together as a kit for detecting an mRNA.

[00415] The nucleic acid can be labeled, if desired, to make a population of labeled mRNAs. In general, a sample can be labeled using methods that are well known in the art (e.g. , using DNA ligase, terminal transferase, or by labeling the R A backbone, etc.; see, e.g., Ausubel, et al, Short Protocols in Molecular Biology, 3rd ed., Wiley & Sons 1995 and Sambrook et al, Molecular Cloning: A Laboratory Manual, Third Edition, 2001 Cold Spring Harbor, N.Y.). In certain embodiments, the sample is labeled with fluorescent label. Exemplary fluorescent dyes include, but are not limited to, xanthene dyes, fluorescein dyes, rhodamine dyes, fluorescein isothiocyanate (FITC), 6-carboxyfluorescein (FAM), 6-carboxy-2',4',7',4,7- hexachloro fluorescein (HEX), 6- carboxy-4',5'-dichloro-2',7'-dimethoxyfluorescein (JOE or J), N,N,N',N'-tetramethyl-6-carboxyrhodamine (TAMRA or T), 6-carboxy-X-rhodamine (ROX or R), 5- carboxyrhodamine 6G (R6G5 or G5), 6-carboxyrhodamine 6G (R6G6 or G6), and rhodamine 110; cyanine dyes, e.g. Cy3, Cy5 and Cy7 dyes; Alexa dyes, e.g. Alexa-fluor-555; coumarin, diethylaminocoumarin, umbelliferone; benzimide dyes, e.g. Hoechst 33258;

phenanthridine dyes, e.g., Texas red; ethidium dyes; acridine dyes; carbazole dyes; phenoxazine dyes; porphyrin dyes; polymethine dyes, BODIPY dyes, quinoline dyes, pyrene, fluorescein chlorotriazinyl, R110, Eosin, JOE, R6G, tetramethylrhodamine, lissamine, ROX, and

napthofluorescein.

[00416] The nucleic acids may be present in specific, addressable locations on a solid support; each corresponding to at least a portion of mRNA sequences of a biomarker.

[00417] In certain embodiments, an mRNA assay comprises the steps of 1) obtaining surface- bound probes for one or more biomarkers; 2) hybridizing a population of mRNAs to the surface- bound probes under conditions sufficient to provide for specific binding; (3) removing unbound nucleic acids in the hybridization step; and (4) detecting the hybridized mRNAs.

[00418] Hybridization can be carried out under suitable hybridization conditions, which may vary in stringency as desired. Typical conditions are sufficient to produce probe/target complexes on a solid surface between complementary binding members, i.e., between surface- bound probes and complementary mRNAs in a sample.

[00419] In certain embodiments, stringent hybridization conditions are used. Standard hybridization techniques {e.g., under conditions sufficient to provide for specific binding of target mRNAs in the sample to the probes) are described in Kallioniemi et al., Science 258:818- 821 (1992) and WO 93/18186, the disclosure of each which is incorporated herein by reference in its entirety. Several guides to general techniques are available, e.g., Tijssen, Hybridization with Nucleic Acid Probes, Parts I and II (Elsevier, Amsterdam 1993). For descriptions of techniques suitable for in situ hybridizations, see Gall et al. Meth. Enzymol., 21 :470-480 (1981); and Angerer et al. in Genetic Engineering: Principles and Methods (Setlow and Hollaender, Eds.) Vol 7, pages 43-65 (Plenum Press, New York 1985). Selection of appropriate conditions, including temperature, salt concentration, polynucleotide concentration, hybridization time, and stringency of washing conditions, depends on experimental design, including the source of a sample, the identity of capture agents, the degree of complementarity expected, etc., and may be determined as a matter of routine experimentation for those of ordinary skill in the art.

[00420] After the mRNA hybridization procedure, the surface bound polynucleotides are washed to remove unbound nucleic acids. Washing may be performed using any convenient washing protocol. In certain embodiments, the washing conditions are stringent. The hybridization of the target mRNAs to the probes is then detected using standard techniques.

4.5.2 PCR-based Methods of Detecting mRNA Levels in a Sample

[00421] In certain embodiments, the mRNA level of a biomarker is determined using a PCR- based method. Examples of PCR assays can be found in U.S. Pat. No. 6,927,024, the disclosure of which is incorporated by reference herein in its entirety. Examples of RT-PCR methods can be found in U.S. Pat. No. 7,122,799, the disclosure of which is incorporated by reference herein in its entirety. Examples of fluorescent in situ PCR methods can be found in U.S. Pat. No.

7,186,507, the disclosure of which is incorporated by reference herein in its entirety.

[00422] In certain embodiments, real-time reverse transcription-PCR (qRT-PCR) is used for both the detection and quantification of mRNAs (Bustin, et al., Clin. Sci., 2005, 109, 365-379). Quantitative results obtained by qRT-PCR are generally more informative than qualitative data. Examples of qRT-PCR-based methods can be found in U.S. Pat. No. 7,101,663, the disclosure of which is incorporated by reference herein in its entirety.

[00423] In contrast to regular reverse transcriptase-PCR and analysis by agarose gels, realtime PCR gives quantitative results. An additional advantage of real-time PCR is the relative ease and convenience of use. Instruments for real-time PCR, such as Applied Biosystems 7500, are available commercially. The reagents for real-time PCR, such as TaqMan Sequence

Detection chemistry, are also commercially available.

[00424] To determine the cycle number at which the fluorescence signal associated with a particular amplicon accumulation crosses the threshold (referred to as CT), the data can be analyzed, for example, using a 7500 Real-Time PCR System Sequence Detection software vl .3, using the comparative CT relative quantification calculation method. Using this method, the output is expressed as a fold-change in expression levels. In some embodiments, the threshold level can be selected to be automatically determined by the software. In some embodiments, the threshold level is set to be above the baseline, but sufficiently low to be within the exponential growth region of an amplification curve.

[00425] Techniques known to one skilled in the art may be used to measure the amount of an RNA transcript(s). In some embodiments, the amount of one, two, three, four, five or more RNA transcripts is measured using deep sequencing, such as ILLUMINA® RNASeq, ILLUMINA® next generation sequencing (NGS), ION TORRENT™ RNA next generation sequencing, 454™ pyrosequencing, or Sequencing by Oligo Ligation Detection (SOLID™). In other embodiments, the amount of multiple RNA transcripts is measured using a microarray and/or gene chip. In certain embodiments, the amount of one, two, three or more RNA transcripts is determined by RT-PCR. In other embodiments, the amount of one, two, three or more RNA transcripts is measured by RT-qPCR. Techniques for conducting these assays are known to one skilled in the art.

[00426] In some embodiments, a statistical analysis or other analysis is performed on data from the assay utilized to measure an RNA transcript or protein. In certain specific embodiments, p value of those RNA transcripts or proteins differentially expressed is 0.1, 0.5, 0.4, 0.3, 0.2, 0.01, 0.05, 0.001, 0.005, or 0.0001. In specific embodiments, a false discovery rate (FDR) of 10%, 9%, 8%, 7%, 6%, 5%, 4%, 3%, 2%, 1% or less is selected.

4.5.3 Methods of detecting polypeptide or protein biomarkers

[00427] When the biomarker is a protein, polypeptide, or peptide, several protein detection and quantitation methods can be used to measure the level of the biomarker. Any suitable protein quantitation method can be used in the methods provided herein. In certain embodiments, antibody-based methods are used. Exemplary methods that can be used include, but are not limited to, immunoblotting (western blot), enzyme-linked immunosorbent assay (ELIS A), immunohistochemistry, flow cytometry, cytometric bead array, and mass spectroscopy. In certain embodiments, a biomarker protein is detected using mass spectroscopy. Several types of ELIS A are commonly used, including direct ELIS A, indirect ELIS A, and sandwich ELIS A.

5.4 Proteomic screening for proteins up-regulated or down-regulated in response to Compound A treatment in Focus and JHH4 cell lines

[00474] HCC cell lines (excised xenograft tumors of HAK-IAJ and Focus) were treated with either with DMSO, or Compound A for either once (single) or multiple times. Cells were harvested at 24 or 72 hours time points, and proteins were fractionated using a basic pH reverse gradient method. Fractionated samples were labeled using a Tandem Mass Tag (TMT) method. Relative abundance was calculated.

[00475] The results of the proteomics screening study are shown in FIG. 1 A-C. FIG. 1 A shows the relative abundance of the differentially abundant proteins after Compound A treatment compared with the DMSO treatment in Focus cells. FIG. IB shows the relative abundance of the differentially abundant proteins after Compound A treatment compared with the DMSO treatment in HAK-IAJ cells. FIG. 1C shows proteins commonly differentially abundant at 24 hours after treatment with Compound A in both Focus and HAK-1AJ cell lines, e.g., WIBG, KAT1, Nestin, PARP4, and MVP.

[00476] Based on the proteomic screening study, certain proteins upregulated in response to Compound A treatment include Nestin, KATl/CCBLl, and WIBG, and certain proteins downregulated in response to Compound A treatment include MVP, PARP4, ZFP91, and ZNF198.

Cells were harvested and proteins were prepared from the cells for proteomics analysis. The growth of the cells on control plates was also analyzed. In particular, cells were plated in media containing either DMSO or Compound A. Cells were cultured for certain time, and then were harvested onto filter plates. After the plates have dried, scintillation fluid was added to the plates and read on a Top-count reader.

[00478] FIG. 2A shows the level of CRBN and ZFP91 in control plates and proteomic preparations (established) in 3D Focus cells treated with Compound A for various times.

FIG. 2B shows the colony number and total colony area of control plates. FIG. 3A shows the level of CRBN and ZFP91 in control plate and proteomic preparation (established) in 3D JHH4 cells treated with Compound A for various times. FIG. 3B shows the colony number and total colony area of control plates. As shown, Compound A treatment reduced the colony number and the total colony area in both cell lines. The levels of CRBN and ZFP91 in control plate and proteomic preparation were analyzed using beta-actin as a control. As shown, in both HCC cell lines, Focus and JHH4, treatment with Compound A increased the level of CRBN protein, and reduced the level of ZFP91 protein. 5.6 Western Analysis shows the level of ZFP91 reduces in response to Compound A or Compound B treatment in Focus and JHH4 cell lines

[00479] Focus cells were cultured for 18 days either continuously for 18 days in the medium containing DMSO, Compound A, or Compound B, or cultured for 7 days prior to treating with DMSO, Compound A, or Compound B for 11 days. Then cells were harvested and were treated in 200 μΐ cold cell lysis buffer ( 1% Triton X-100 from Cell Signaling supplemented with protease inhibitors and phophatase inhibitors from Roche) to generate cell lysate. Proteins from cell lysate were separated by 4-12% nupage gels (Invitrogen) and transferred to nitrocellulose membranes. Immunoblots were then probed with antibodies recognizing CRBN, ZFP91 (LSBio) and β-actin (Li-Cor). Signals were detected with a Li-Cor Odyssey Imager. The results of the western blot were shown in FIG. 4A. As shown, the level of ZFP91 reduced in response to treatment with Compound A or Compound B.

[00480] HCC cells from both Focus and JHH4 cell lines in 2D setting treated with Compound A for 6 hours, 24 hours, and 72 hours, and JHH4 cells in 3D setting treated with Compound A for 15 days were also analyzed by western blot. Cells were harvested and were treated in 200 μΐ cold cell lysis buffer (1% Triton X-100 from Cell Signaling supplemented with protease inhibitors and phophatase inhibitors from Roche) to generate cell lysate. Proteins from cell lysate were separated by 4-12% Nupage gels (Invitrogen) and transferred to nitrocellulose membranes. Immunoblots were then probed with antibodies recognizing CRBN, ZFP91

(LSBio), P-TBK1, and β-actin (Li-Cor). Signals were detected with a Li-Cor Odyssey Imager. The results were shown in FIG. 4B. As shown, the level of ZFP91 reduced in response to treatment with Compound A for 6 hours, 24 hours, or 72 hours in both cell lines in 2D setting. The level of ZFP91 also reduced in response to treatment with Compound A for 15 days in JHH4 in 3D setting. The level of CRBN increased in response to treatment with Compound A for 6 hours, 24 hours, or 72 hours in both cell lines in 2D setting. The level of CRBN also increased in response to treatment with Compound A for 15 days in JHH4 in 3D setting. It was also noted that P-TBK1 was upregulated in 3D setting upon Compound A treatment. ZFP91 degradation induced by various doses of Compound A for various time periods was also tested in both Focus and JHH4 cells, as shown in FIG.4C. ZFP91 degradation in response to Compound A treatment is also confirmed using siRNAs targeting to ZFP91, as shown in FIG.4D. 5.7 ZFP91 is Down-regulated in Response to Treatment Compounds in a CRBN Dependent Pathway in Focus and JHH4 Cells

[00481] As shown in FIG. 5A, Western Analysis shows MG132 and MLN4924 block the reduction of the level of ZFP91 in response to Compound A treatment in HCC cell lines. HCC cells from both Focus and JHH4 cell lines in 2D setting were first treated with 10 μΜ MG132 or MLN4924 for 1 hour, and then were treated with 5 μΜ DMSO or 5 μΜ Compound A for 6 hours. Cells were harvested and were treated in cell lysis buffer to generate cell lysate. Proteins from cell lysate were separated by gel electrophoresis and transferred to nitrocellulose membranes. Immunoblots were then probed with antibodies recognizing CRBN, ZFP91 (LSBio), and β-actin (Li-Cor). The results were shown in FIG. 5 A, and as shown, both 10 μΜ MG132 or MLN4924 inhibited ZFP91 degradation. MG132 activates c-Jun N-terminal kinase (JNK1), which initiates apoptosis. MG132 also inhibits NF-κΒ activation with an IC50 of 3 μΜ and prevents β-secretase cleavage. MLN4924 is a NAE1 inhibitor that blocks the activity of Cullin Ring Ligases (CRLs), such as CRL4CRBN. Both MG132 and MLN4924 inhibit CRBN activities, and thus these results indicate that ZFP91 is down-regulated in response to treatment compounds in a CRBN dependent pathway.

[00482] As shown in FIG. 5B, the level of ZFP91 decreased in response to Compound A treatment in Focus and JHH4 cells treated with a protein synthesis inhibitor— 100 ug/ml cycloheximide (CHX). This result indicates that Compound A accelerates ZFP91 turnover through proteasome-mediated degradation.

[00483] As shown in FIG. 5C, knocking down of CRBN in Focus and JHH4 cells reversed the effect of Compound A on ZFP91 degradation. Similarly, as shown in FIG.5D, knocking down of CRBN also reversed the effect of Compound B on ZFP91 protein level. Again, these results indicate that ZFP91 is down-regulated in response to treatment compounds in a CRBN dependent pathway.

5.7 ZFP91 is Down-regulated in Response to Treatment Compounds in a CRBN Dependent Pathway in Hep3B Cell Lines

[00484] The change of ZFP91 level in response to Compound A or Compound B treatments was also evaluated in human hepatoma Hep3B cell lines. Hep3B cells were treated with Compound A or Compound B, and cells were harvested and treated in lysis buffer to generate cell lysate. Proteins from cell lysate were separated by electrophoresis gel and transferred to nitrocellulose membranes. Immunoblots were then probed with antibodies recognizing CRBN, ZFP91, and β-actin. Signals were detected with a Li-Cor Odyssey Imager. The results were shown in the upper panel of FIG. 6A. As shown, ZFP91 is down-regulated in response to treatment with Compound A or Compound B. Similarly to Focus and JHH4 cells, MG132 and MLN4924 blocked the reduction of the level of ZFP91 in response to Compound A or

Compound B treatment, as shown in the lower panel of FIG. 6A. It was noted that Hep3B cells were sensitive to Compound B, but not to Compound A, as shown in FIG. 6B. Thus, ZFP91 may be degraded in response treatment compounds regardless of growth response of the cells to the treatment compounds.

5.8 ZFP91 is Down-regulated in Response to Treatment Compounds in a CRBN Dependent Pathway in Glioblastoma Cell lines

[00485] The change of ZFP91 level in response to treatment compounds was evaluated in other solid tumor cell lines, e.g., glioblastoma (GBM) cell lines. U87 human primary glioblastoma cells and SNB 19 glioma cells were treated with Compound A or lenalidomide, and cells were harvested and treated in lysis buffer to generate cell lysate. Proteins from cell lysate were separated by electrophoresis gel and transferred to nitrocellulose membranes. Immunoblots were then probed with antibodies recognizing ZFP91 and β-actin. Signals were detected with a Li-Cor Odyssey Imager. The results were shown in FIG. 7A. As shown, ZFP91 is down- regulated in response to treatment with Compound A or lenalidomide. As shown in the left panel of FIG.7B, Compound A significantly inhibits U87 tumor growth at 3 and 30 mg/kg qd. Immunostaining assay showed that Compound A degraded ZFP91 in U87 xenograft tissue as shown in the right panel of FIG. 7B. Similarly to HCC cells, MG132 and MLN4924 blocked the reduction of the level of ZFP91 in response to treatment compounds in U87 and SNB 19 cells, as shown in of FIG. 7 A, indicating that the treatment compounds reduced the level of ZFP91 in a CRBN dependent pathway.
